First, MMA Weekly reports that a welterweight bout between Diego Sanchez and Thiago Alves will take place at UFC 90 (October 25th, Chicago); the UFC hasn’t officially announced any of the fights on the card yet. Originally, Sanchez/Alves was rumored to take place at UFC 89 in Birmingham, England, but with that lineup filling out it looks like the Nightmare vs. the Pitbull will be used to anchor the UFC’s first show in Chi-town.
